Honduran coup leaders have raised the possibility of early elections to solve the country's political crisis, hours before the head of the Organisation of American States (OSA) is due to arrive.
Since President Manuel Zelaya was ousted on Sunday the country has been rocked by growing demonstrations and the freezing of international aid.
Foreign ambassadors have been recalled, prompting some diplomats to call for early elections as a way out of the crisis.
That suggestion was given added credence on Thursday, when interim leader Roberto Micheletti backed down from his hardline stance of insisting that general elections would take place on November 29, as planned.
The elections could be advanced, Micheletti told journalists.
"As long as it's within the law, there's no problem. I'd have no objection if that was a way to solve this kind of problem," he said.
OAS chief Jose Miguel Insulza was due to pay a flying visit to the increasingly polarised country on Friday, shortly before the end of an OAS deadline for Honduras to bring back Zelaya or face being kicked out of the body.
Protests have increased throughout the week with daily lives disrupted by night-time curfews. These suspend some freedoms guaranteed by the constitution and the country's 7.5 million inhabitants have become increasingly frustrated.
The army clashed with demonstrators in northern Honduras on Thursday for the first time in three days.
Insulza meanwhile said he faced a massive challenge following defiant statements from the coup leaders who have threatened to arrest Zelaya if he returns to the country.
"I cannot say I am confident. I will do everything I can but I think it will be very hard to turn things around in a couple of days," Secretary General Insulza told reporters after a regional meeting in Guyana.
Insulza planned to talk to select members of the Supreme Court and Congress, which along with the army, clashed with Zelaya over his plans to change the constitution before sending him away on Sunday.
Insulza dismissed any idea of negotiating with the instigators of the coup.
"We are not going to Honduras to negotiate. We are going to Honduras to ask them to change what they have been doing now and find ways in which we can return to normalcy," said Insulza.
Demonstrations turned violent again on Thursday, this time in the country's main economic hub San Pedro Sula, after clashes between baton-wielding soldiers and protesters in the capital at the start of the week.
A Zelaya ally and deputy said the army had shot at protesters, injuring two.
A local police commissioner said some protesters had been detained and the army had intervened after demonstrators started attacking shops.
Thousands took part in a separate demonstration in favour of Micheletti.
As thousands of pro-Zelaya protesters came out in Tegucigalpa, Zelaya said in Panama that a string of personalities would join him when he returned to the country, including Nobel Prize winners and presidents. He did not mention a return date.
The international community meanwhile has placed further pressure on Honduras.
The Swedish EU presidency said all EU countries with embassies in Honduras had withdrawn their ambassadors.
Central American countries and Latin American leftists, including Venezuela - Zelaya's main supporter - Cuba, Ecuador, Bolivia and Nicaragua have announced similar measures, as well as Colombia.
The Inter-American Development Bank on Wednesday halted aid, following a similar move by the World Bank. And key ally the United States indicated it may follow suit, saying it would wait until Monday before making a decision.
The Pentagon suspended all military activities with Tegucigalpa until further notice, a spokesman said.
Soldiers bundled Zelaya into a plane at dawn last Sunday and sent him to Costa Rica after a dispute with the country's courts, politicians and army over his attempts to change the constitution to allow him the possibility of a run for a second term.
